Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe, level area, and the parking brake is applied.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Sub-steps:
1. Inspect the battery terminals for corrosion. Clean them with a wire brush if necessary.
2. If the battery voltage is below 12.4 volts or it is old (over 3-5 years), replace the battery.
3. To replace, remove the positive terminal first, then the negative terminal.
4. Remove any battery hold-down clamps and lift the battery out.
5. Install the new battery by positioning it in the tray and securing it with clamps.
6. Connect the positive terminal first and then the negative terminal.

3. Starter Motor Inspection

Sub-steps:
1. Locate the starter motor, typically found near the bottom of the engine.
2. Check the electrical connections to the starter for corrosion or looseness.
3. If accessible, perform a bench test on the starter motor by applying direct battery voltage.
4. If the starter does not engage or spin, replace it with a new unit.
5. Reinstall the starter by securing it with bolts and reconnecting the electrical terminals.

4. Final Assembly

Sub-steps:
1. Reconnect the negative battery terminal.
2. Start the vehicle to check if the issue is resolved.
3. Ensure all tools are removed from the engine bay and the area is clean.
